By What is a Nondihydropyridine calcium channel blocker?
Nondihydropyridine calcium channel blockers are a class of antiarrhythmic drugs used to treat tachydysrhythmias (abnormal cardiac rhythm with a rate greater than 100 beats per minute) and hypertension (high blood pressure).
Is propranolol a calcium channel blocker?
Thus propranolol and betaxolol are equipotent vasorelaxant drugs in retinal microartery, both probably acting via Ca2+ channel blockade. This activity (that shows no stereospecificity) thus appears to be a more general property of beta-blockers.
What type of calcium channel blocker is diltiazem?
Diltiazem is a nondihydropyridine CCB that produces its antihypertensive effect primarily by relaxation of vascular smooth muscle and the resultant decrease in peripheral vascular resistance.
What are long-acting calcium channel blockers?

Avoid grapefruit products while taking certain calcium channel blockers. Grapefruit juice interacts with the drug and can affect heart rate and blood pressure. This can cause symptoms such as headaches and dizziness.
What is a natural calcium channel blocker?
Magnesium is a natural calcium channel blocker, blocks sodium attachment to vascular smooth muscle cells, increases vasodilating PGE, binds potassium in a cooperative manner, increases nitric oxide, improves endothelial dysfunction, causes vasodilation, and reduces BP.
